Simple passcodes are more convenient than they are secure. If you really want to be safe, go with a strong password.

Although Apple has numerous protections in place to keep 6-digit — and even old-style 4-digit — safe, including time delays and optional erasure, typing in a short series of numbers remains more about convenience than it does security. The ability to brute-force such — in other words, try every possible combination in sequence until the right one is found — has been and may one day again become possible for anyone with the right access and equipment.

If security is what you’re really after, then what you really want to use is a strong passcode.

Before you begin, figure out the long, strong alphanumeric you want to use. If you need help choosing one, check out this article from AgileBits and Steve Gibson’s page on haystacks:

The should be long enough that it’s extremely difficult to crack with current technology, but not so long that you can’t remember it or enter it accurately when you need to.

Launch Settings.Tap Passcode (or Touch ID & Passcode).Enter your existing 4-digit or 6-digit passcode if you have one.Tap Change PasscodeRe-enter your existing passcode if you have one.Tap Passcode Options.

I’ve used as short as eight characters (letters, numbers, and symbols mixed), as many as twenty, but often somewhere in between.

If you’re going anywhere you suspect might be risky, you can also temporarily deactivate Touch ID for unlock, which will force password entry to access your iPhone or iPad. That way no one can try to touch your finger to the Home button either while you’re sleeping or otherwise immobilized.

Again, less but more . Most people will, hopefully, won’t have cause to worry about all these options but everyone should take comfort in them being there.
